[NB] EM dash

And if you type 3 hyphens and a space, you also get an em-dash. If you type 4 hyphens and a space you get an em-dash and another character (which right now renders as an unrenderable box). I’m not sure this is deliberate. If you type a continuous string of hyphens, that sequence will repeat ad nauseum.

Scriv Beta 16 does not have this behavior in the document name/title or the synopsis, but it does in notes and documents.
